AK Sometime when your system isn't at its peak, just take the segment offline. Then wait a little while and check the status. Oracle won't take the segment offline as long as active processes are using it. Oracle won't let you drop it until it is able to take it offline.

[EMAIL PROTECTED] -----Original Message----- Sent: Friday, March 14, 2003 3:54 PM To: Multiple recipients of list ORACLE-L I have recently found that one temporary rollback segment in system tablespace is having more then 600 extnets . It looks like previous dba created this rollback segment at the time of db creation and forgot to take it offline . Now how do I find it this rollback segment is being used actively . I see values in gets , writes from v$rollstat view . What step should I take to drop this rollback segment . What implication might have if I take this offline ? I want to relase the space taken by this rollback segment ( >600 extents ..thats big ) , so just taking offline wont do this. Are there any views accessible from system( no sys) account which can tell me which trasaction is using which rollback segment . thanks -ak -- Please see the official ORACLE-L FAQ: http://www.orafaq.net -- Author: DENNIS WILLIAMS INET: [EMAIL PROTECTED] Fat City Network Services -- 858-538-5051 http://www.fatcity.com San Diego, California -- Mailing list and web hosting services --------------------------------------------------------------------- To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB ORACLE-L (or the name of mailing list you want to be removed from).
